The British Columbia Marine Conservation Analysis (BCMCA) is a collaborative project assembling and analyzing spatial information about Canada's Pacific Ocean. The overall goal of the BCMCA is to identify marine areas of high conservation value and marine areas important to human use. Results of the project are intended to inform and help advance marine planning initiatives in BC by providing collaborative, peer-reviewed scientific analyses based on the best ecological and human use spatial data at scales relevant to a BC coast-wide analysis.

Purpose:

The purpose of this dataset is to identify areal extents of Shrimp Observed Catch Density (kg/m2) from 2009 that helps inform the marine feature identified at the BCMCA Marine and Anadromous Fish Workshop. Data presented as 2 x 2 km planning units for Marxan analysis.

Shrimp Trawl Observed Catch Density records were saved to a geodatabase table and joined to the BCMCA planning units. The joined file was extracted to a new feature class and extraneous fields were removed. An ID field was added to hold the Marxan ID.

Process_Description:

A new field "kg_perKM2_perTow" added to hold the density corrected for effort. This field was calculated as: (kg_per_square_meter)*1,000,000/count_of_tows.
